This paper presents the first sub-percent precision lattice QCD calculation of the next-to-leading order hadronic vacuum polarization contribution to the muon anomalous magnetic moment, yielding a result of that is twice as precise as the 2025 White Paper estimate and shows a significant 4.8 tension with data-driven evaluations excluding the CMD-3 measurement.
This paper extends a single-flavon -lattice Froggatt-Nielsen framework to the lepton sector, successfully generating charged-lepton mass hierarchies and a normal-ordered neutrino spectrum while predicting a distinct two-branch correlation between the atmospheric mixing angle and the CP-violating phase , with a lower-octant solution (, ) favored by theoretical priors.
This paper introduces a nonperturbative Hamiltonian framework that rigorously connects finite-volume lattice QCD spectra to experimental scattering observables, successfully demonstrating its utility by extracting robust resonance parameters for the meson through a unified analysis of coupled and systems.
This paper proposes an extended left-right symmetric model incorporating an additional $SU(2)$ gauge symmetry and vector-like fermions to explain neutrino mass hierarchies through distinct seesaw mechanisms, while utilizing LHC Run II data to establish lower mass limits on the new and gauge bosons based on their decay channels.
This paper investigates a generalized gauged -Maxwell theory where integrating out a massive Dirac fermion induces a non-polynomial, logarithmic magnetic permeability, enabling the derivation of BPS vortex solutions with quantized magnetic flux that highlight the interplay between target-space geometry and the induced permeability.
This paper presents a physics-informed neural network approach to extract a universal small- dipole scattering amplitude directly from global DIS and photoproduction data without rigid parametric assumptions, successfully resolving the long-standing tension between total and charm cross-section channels while providing a smooth, non-negative input for Color Glass Condensate phenomenology.
This paper investigates how future lepton colliders can probe the CP properties of axion-like particle (ALP) interactions with photons by analyzing the azimuthal angle difference between final-state electrons in the process, demonstrating that this observable can distinguish between CP-conserving, CP-violating, and mixed interaction structures with projected sensitivities exceeding current electron electric dipole moment constraints.
This paper calculates enhanced electroweak, QCD, and QED radiative corrections to the nucleon coupling constants and , providing updated relations between lattice-QCD and physical values that yield a total correction of approximately 3.5% to 5.6% and predict a physical axial charge of 1.265(26) or 1.240(9) depending on the input methodology.
This paper proposes a -based inverse seesaw model that successfully explains neutrino mass hierarchies and cobimaximal mixing patterns while accounting for the observed baryon asymmetry of the Universe via leptogenesis in the normal mass hierarchy scenario.
The paper demonstrates that the final state of a binary black hole merger corresponds with remarkable accuracy to the configuration that maximizes the instability rate of null geodesics, suggesting a deep connection between merger dynamics and the efficiency of photon ring scrambling.
